JOHN A. MOCOLLUM AND BENJAMIN F. BURT, OF RIVERSIDE, CALIFORNIA- APPARATUS FOR THE MANUFACTURE OF GAS.

SPECIFICATION forming part of Letters Patent No. 430,807,- dated June 24, 1890.

Application filed June 25, 1889. Serial No. 315,455. (No model.)

To all whom it may concern:

Be it known that we, JOHN A. MoOoLLUM and BENJAMIN F. BURT, of Riverside, in the county of San Bernardino and State of California, have invented a new and Improved Apparatus for the Manufacture of Gas, of which the following is a full, clear, and exact description.

The invention relates to apparatus for the manufacture of gas such as shown and described in the Letters Patent No. 395,449, dated January 1, 1889, and granted to John A. McOollum.

The object of the invention is to provide a new and improved apparatus for the rapid and economical manufacture of water-gas from superheated steam and oil.

The invention consists in certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a longitudinal sectional elevation of the furnace on the line to ac of Fig. 1.

The improved gas-making apparatus is provided with a furnace A, having two compartments B and O, located one above the other, and divided by an arch D, having near one end an aperture D for establishing communication between the two compartments B and 0. Suitable doors lead into the ends of the compartments B and O, and the former is ad ditionally provided with grate-bars B,below which is formed an ash-pit E, into which discharges a pipe F, provided with a valve F, and connected with a pipe F leading to a blasting-engine of any approved construction. By thus forming doors at both ends of the compartment B first one end and then the other may be charged, thereby permitting us to have one end of our fire a cherryred at all times; and so with the lime-com partment first one end and then the other may be freshly charged.

Into the sides of the compartment B, directly under the arch D, discharge the oilpipes G and G, each provided with a valve G and both connected with a pipe G leading to an oil-tank G located a suitable distance above the furnace A, so that the oil flows under pressure into the compartment B of the furnace A. The oil-tank G is provided with a supply-pipe G connected with a suitable source of supply an d provided with a valve G.

From the top of the compartment 0, at the end opposite the opening D, a pipe H leads to the fixing-chamber I in the following manner: From the end of the pipe H extends downward a pipe H, having a branch pipe l-I passing through the side wall of the fix ing-chamber I and discharging into the fireplace J. From the end of the pipe II also leads a small pipe H passing through the side wall of the fixing-chamber I and discharging into a fire-place K above the fireplace J. The pipe H is provided with a 'valve H for connecting said pipe with the pipe H and disconnecting it from the same. Above the fireplaces J and K extend the checker-bricks L and N, respectively.

From the top of the fixing-chamber I leads a pipe 0, extending upward and provided with a valve P, which when open permits the pipe 0 to discharge into the chimney Q. From the side of the pipe 0 a pipe R extends downward, leading into awasher S of any approved construction.

From the air-supply pipe F leads a short branch pipe U, provided with a valve U, and extending into the bottom of the fire-place J. A similar branch pipe V leads from the end of the supply-pipe F and is provided with a valve V. The branch pipe V leads into the fire-place K. A steam pipe T, connected with a suitable source of supply, passes through the pipe 11 and discharges into the ash-pit E.

The operation is as follows: On the top of the arch D is placed a suitable quantity of lime, and on the grate-bars B a coal or coke fire is started. The valves G2 are closed, so that no oil is passed into the compartment B. The valves H F, and P are opened, and the blasting engine is set in motion, so that a blast of air passes from the pipe F into the pipe F, and from the latter through the fire in the compartment B, whereby the heat generated passes upward through the opening B into the compartment 0, and from the latter through the pipes H, H, H and H into the fire-places J and K of the fixing-chamber I. The heat, passing through the fire-places J and K, heats the bricks L and N, and finally the residue of the'heat passes through the pipe into the chimney Q. When the checkerbricks L and N are heated to the proper degree, the valves P and H are closed, after which the valves U and F are closed, so as to stop the blast into the fire-place J and the compartment B. The steam is now permitted to pass through the pipe T into the ash-pit E and through the coke or coal fire on the gratebars B. The steam on passing through this fire generates a gas, consisting, principally, of carbon dioxide and carbon monoxide, according to the fuel, coal, or coke used. At the same time the valves G2 in the pipes G and G are opened, so that oil flows from the tank G- into the top of the compartment B, in which it is burned and forms a light and a heavy hydrocarbon gas, which mix with the gases above mentioned. The mixture of gases passes through the aperture D into the top compartment 0 and over the lime contained in the same, so that all sulphur contained in the gases is taken up by the lime and retained. The partly-purified gases now pass from the compartmentC into the pipe H, and from the latter through the pipes H and H into the fire-place J, and through the heated checker-bricks L into the fire-place K, and from the latter through the checker-bricksN into the pipe 0, connected by the pipe R with the washer S, in which latter the, gases are purified. When the fixing-chamber I has cooled off, the valves G are again closed, and the generator is heated in the manner above described. By this reheating the sulphur previously taken up by the lime in the compartment C is burned and passes off with the heat to the pipe H and to the fixing-chamber I, and from the latter it passes into the chim between said compartments at the ends opposite said outlet, of the oil-pipes discharging into the coal-compartment, a steam-pipe and an air-blast pipe entering the coal-compartment below its grate, and a fixing-chamber to which said outlet-pipe leads, substantially as set forth.
